The pancreas secretes trypsin and chymotrypsin enzymes which continue breakdown proteins into smaller peptides and some single amino acids. Carboxypeptidase also secreted by the pancreas splits single amino acids from the carboxyl end of proteins.
Bile, which contains a mix salts, is secreted by the liver . Bile salts help to continue digestion of fats by attaching to small fat droplets, preventing them from coalescing into larger droplets, thereby increasing their surface area so that they can be further broken down by lipase enzymes.
Asmara I understand how you feel. I have suffered from depression myself for three decades. Did you know it’s often genetic? Someone else in your family suffers as well. There is help though. Through therapy and sometimes medications, you can find relief. The first step is to know you’re not alone and find someone whom you can talk to. You need a support system. Journaling can be therapeutic as well. Most of the time a person with depression needs to realize why they are mostly depressed and come up with coping strategies to get past this feeling. When you think you can’t get over it- you can. Over 50% of human beings suffer from anxiety and depression at some point in their life. Don’t try to battle this on your own; confide in a friend or adult who you can trust.
