Document Summary
Feb. 5 th - intro to proteins (guest lecturer) Proteins are large, complex molecules with many functions. Contain carbon, hydrogen, oxygen and nitrogen grouped together in long strands of amino acids. In bones (osteocalcin), blood (hemoglobin), hormones (testosterone), muscle(myosin), organs (lipoproteins made in liver that travel to the blood) And of course, enzymes are proteins (ie, salivary amylase- digests starch into smaller carbohydrates, or pancreatic lipase- digests triglycerides) Note*: anything that ends in ase is an enzyme. Amino acids are different because they contain a side chain (ch3)- makes the amino acids different from one another. Glutamate does not have a side chain, alanine does- the composition of the side chain is how we can distinguish one aa from another. 9 are essential (the body can"t make them, we have to eat them) 11 are non-essential (our body can make these through transanimation) All nutrients are important, not all are essential (not all have to be consumed)
