9568485021What makes protein different from CHO and fat?presence of nitrogen, amino acids, and ab 20 different amino acids make up most of the proteins in living tissue.0
9568496301amino acidsbuilding blocks of protein1
9568509583All 20 amino acids have the _______ chemical backbone.SAME2
9568512363chemical backbone of amino acidscarbon atom + amine group + acid group3
9568523182Amino acids differ in their ________ _______.side chains4
9568525796enzymesthe vast majority of chemical reactions that occur in the body are catalyzed by enzymes.5
9568544178transportersmost substances move in and out of cells with the aid of protein transporters. Many nutrients are also carried in the blood attached to transport proteins6
9568567377hormones and regulationnumerous protein hormones (like insulin) and many other related proteins regulate the majority of the processes in our body. Proteins also allow the body to sense and react to various stimuli.7
9568590648structure and movementproteins provide critical structural components of the body and even within its cells. Contractile proteins account for 50% of total proteins in skeletal muscle.8
9568604199acid-base balanceproteins buffer body fluids to aid in maintaining a proper pH9
9568612771fluid balanceproteins regulate the distribution of fluids throughout various compartments of the body.10
9568631019antibodiesantibodies are critical for the body's defense against viruses and bacteria11
9568636730proteinsenzymes, transporters, hormones and regulation, structure and movement, acid-base balance, fluid balance, and antibodies12
9568666472different amino acids join together form ________.proteins; AA's link into long strands that make a wide variety of different proteins13
9568699032slide 7:)14
9568704079protein synthesisDNA->RNA->Protein15
9568721019protein in the food we eatmeats, poultry, seafood, eggs, soy products, nuts, seeds, beans, peas, lentils, and dairy16
9568736334you should eat seafood:twice a week17
9568741947meatless sources of proteinhemp seeds, tofu, tempeh, sprouted grain breads, nut butters, edamame, spirulina18
9568748689milk alternativescow's, almond, coconut, hemp, & soy19
9568764216amino acids must be continually available each daybuilding new tissue proteins, grow new cells, and replace worn-out cells20
9568780246the entire process of protein breakdown, recovery, and synthesis=protein turnover21
9568785340how much protein people need depends on:body size, stage of growth, athletes, and body's health22
9568791394body sizeDRI= 0.8 grams/kg; AMDR= 10-35% of energy (calories)23
9568802434stage of growthhigher for infants and growing children24
9568805945athletes1.2-1.7 grams/kg25
9568808519body's healthinfection or manipulation greatly increase protein needs26
9568816872RDA=0.8 g/kg body weight27
9568821089high quality proteins: provides enough of allessential amino acids28
9568830364high quality proteins: quality is influenced byamino acid composition and digestibility29
9568847258limiting amino acidsan essential amino acid that is present in dietary protein in an insufficient amount, thereby limiting the body's ability to build protein30
9568873742vegan diets: certain breadsthat glossy top comes from egg wash, while dough's can sneak in honey, egg yolks, even protein from poultry feathers31
9568890401vegan diets: condiments, dresssings, saucesanchovies in Worcestershire sauce, eggs om mayo, dairy in ranch dressing, cheese in store bought pesto32
9568898726vegan diets: sugarsthe process to make refined white sugar involves animal bone char--definitely not vegan.33
9568915631vegan diets: deep-dried foodsyour onion rings could be dredged in an eggy batter or fried in animal fat34
9568929012vegan diets: gummy candies, jell-O, marshmallowsthese sticky sweets most often get their chewy, jiggly texture from gelatin35
9568939128vegan diets: food//drinks with red coloringthat bright red "natural" color comes from the extract of crushed and boiled beetles. Can't make this stuff up.36
9568951678vegan diets: roasted salted peanutsgelatin (protein from the tendons or cows or pigs) is used to help the salt stick to the peanuts37
9568960381Vegan diets: certain alcoholsclear hard liquors= generally safe. imported beers and wines that might be made with a fish gelatin= not so happy hour38
9568973691vegan diets: juicesomega-3, vitamin D-fortified OJ might get those "heart-healthy" boost through ingredients like fish oil and sheep's wool-derived lanolin39
9568988607eating meatless ________ improve its nutrient profiledoesn't40
9568994463replace protein portions with _________ sourcesmeatless41
9569011557if inadequate ___________ or _________ intake, body protein will be broken downcarb; energy42
9569016222amino acids--> glucoseoccurs in the liver (gluconeogenesis); can help maintain blood glucose level; N-containing amine groups are stripped off-->incorporated into urea by the liver-->sent to kidneys for excretion in urine43
9569042282no storage from of _______ exists in the bodyprotein44
9569368986what happens when people consume too little protein?body will slow protein synthesis; increase breakdown of body tissue protein45
9569380559Consequences of protein deficiencyslowed growth; impaired brain and kidney function; weakened immune defenses; impaired nutrient absorption from gi tract46
9569395823protein excessheart disease, kidney issues, weight loss, muscle building, colon and rectal cancers47
9569407689oversupply of amino acidsbody cannot store them; remove and excrete amine groups; use of amino acid residues48
9569425045use of amino acid residuesto meet immediate energy needs; to make glucose for storage as glycogen; to make fat for storage as triglycerides49
