PHRM 221 Lecture 6: Proteins & Fats
Document Summary
Organic compounds composed of carbon, hydrogen, oxygen, nitrogen. Act as source of energy, in the absence of cho and fats. Excess protein glucose or stored as fat. Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophane, valine. Must be supplied by diet (not made by body, or made in insufficient amounts) Animal sources : eggs, milk and dairy products, meat, fish, poultry. Plant sources often deficient in 1 of the eaa. Overcome by mixing different plant proteins throughout the day. Complementary: legumes (isoleucine, lysine) + grains (methionine, tryptophan) High quality protein provides all 9 eaa that the body needs to support our bodies. Amino acid composition/quality : amount of aa it supplies. Composed of carbon, hydrogen, oxygen (similar to cho, but more c, h) Admr: 20-35% of macronutrient intake (mostly from mono & polyunsaturated fats) Provides more than 2x energy of cho or protein. Excess fa stored in adipose tissue (unlimited)
